What is a Tripropylene Glycol (TPG)?

Tripropylene Glycol (TPG) is a colorless, odorless, viscous liquid composed of three propylene glycol units. It is highly miscible with water and many organic solvents. TPG is widely used as a solvent, humectant, and plasticizer in a variety of industries, including personal care products, cosmetics, cleaning agents, paints, and inks. It also serves as a carrier for fragrances and as a heat transfer fluid in industrial systems. Due to its low toxicity and minimal irritation to skin and eyes, TPG is considered a relatively safe chemical for both industrial and consumer applications. It comes in different forms such as monomeric (TPG-M) and technical grade (TPG-T), chosen depending on the application. Additionally, TPG is biodegradable and has a low environmental impact, making it a preferred option for sustainable product formulations.
